FOR MODELS: JGW, JGR AND JGJ SECTION 4 - LUBRICATION AND VENTING
PAGE 4 - 10 1/01
NOTE: BASE RATE REFERRED TO ABOVE IS AS FOLLOWS:
0.4 PINTS/DAY/INCH BORE (0.0074 L/DAY/mm BORE) FOR JGJ FRAMES AND
0.3 PINTS/DAY/INCH BORE (0.0056 L/DAY/mm BORE) FOR JGW AND JGR
FRAMES.
PISTON ROD DIAMETER IS DOUBLED AND TREATED LIKE A CYLINDER FOR
CALCULATING PACKING LUBE RATE. FOR CYLINDERS WITH A TAIL ROD,
THE LUBE RATE FOR EACH OF THE (TWO) PACKINGS IS TO BE CALCU-
LATED SEPARATELY AND BOTH VALUES ADDED TOWARD THE RECOM-
MENDED TOTAL DAILY LUBE RATE.
CYLINDERS HAVE ONE POINT BORE LUBE AS STANDARD, EXCEPT FOR
ALL T CLASS CYLINDERS AND CYLINDERS LARGER THAN 13 INCHES (330
mm) WHICH HAVE MULTI-PORT LUBE AS STANDARD. TOP AND BOTTOM
BORE LUBE IS AVAILABLE AS AN ORIGINAL PURCHASE OPTION. PISTON
ROD PACKINGS FOR HIGH-PRESSURE CYLINDERS HAVE TWO POINT
LUBE. FOR MULTIPLE LUBE POINTS, THE REQUIRED LUBRICANT FOR THE
CYLINDER OR PACKING IS DIVIDED EQUALLY AMONG THE LUBE POINTS.
BREAK-IN LUBE RATE SHOULD BE TWICE THE RECOMMENDED DAILY
RATE (150% MINIMUM); I.E. THE BREAK-IN CYCLE TIME SHOULD BE
APPROXIMATELY ONE-HALF THE NORMAL CYCLE TIME (67% MAXIMUM)
TO INCREASE LUBE RATE. BREAK-IN RATE SHOULD BE MAINTAINED FOR
200 HOURS OF OPERATION.
THE RECOMMENDED LUBE RATES FOR BREAK-IN OR NORMAL OPERA-
TION, IN CYCLES PER SECOND (AS STAMPED ON THE LUBRICATOR BOX
INFORMATION PLATE), ARE CALCULATED AT MAXIMUM COMPRESSOR
SPEED (AS STAMPED ON THE COMPRESSOR INFORMATION PLATE). THE
LUBE RATE MAY BE REDUCED WITH SPEED, (AS COMPRESSOR SPEED IS
REDUCED, CYCLE TIME INCREASES TO REDUCE LUBE RATE):
(RPM
MAX
÷ RPM
RUNNING
) x CYCLE TIME SEC
LUBE PLATE
= CYCLE TIME SEC
RUNNING
REFERENCE THE LUBRICATION SHEETS IN THE ARIEL “PARTS BOOK”
FOR THE CYCLE TIME (SECONDS) VS. RPM (COMPRESSOR SPEED) TABLE
AT VARIOUS RUNNING SPEEDS FOR YOUR UNIT, AT THE STATED GAS
OPERATING CONDITIONS AND LUBRICANT.
SPECIAL LUBRICANT FORMULATIONS ARE AVAILABLE FROM LUBRICANT
SUPPLIERS FOR SPECIFIC APPLICATIONS. SUPPLIERS WHO WILL CER-
TIFY SUITABILITY OF THE FORMULATION FOR SITE CONDITIONS SHOULD
PROVIDE APPROPRIATE DOCUMENTATION. CONTACT ARIEL FOR VERIFI-
CATION OF WARRANTY COVERAGE.
